The overall ZX6017 mode of operation is controlled by the Interface
Configuration Register (
to ATA/IDE mode if the PC_ATA/HOE pin is Low on power-up and into
PCMCIA mode if the pin is High. The default for this register is 00 and
the PC_ATA/HOE pin determines the mode of operation, PCMCIA or
ATA/IDE. Table 4 describes these addressing modes.
To place the ZX6017 into proper Addressing mode, a set of Configuration
Registers and Memory Maps reside on-chip.
The ZX6017 supports all PCMCIA Addressing Modes:
PCMCIA Common Memory Mode
PCMCIA I/O Mode
PCMCIA ATA_IDE Mode
Pass-through ATA/IDE-to-ATA/IDE Mode
This mode is for users who have a 68-pin PCMCIA connector,
but are using ATA/IDE protocol instead of PCMCIA protocol.
